Translation software firm SDL said its performance for the first quarter of 2011 was in line with management expectations for both revenue and operating profit.The group, which provides patent translation software services for Ford, Canon and Dell, said demand conditions overall remain strong."Whilst we continue to see varying demand conditions in different industry verticals and some level of economic uncertainty, overall demand conditions remain robust driven by our geographically diverse customer base and our differentiated, technology-led solutions," SDL said in a company statement.Last month the group announced that it would pay a maiden dividend to reflect its confidence in future trading.---CJ
